Homebrew Discussion Simple ReadOnly Telnet client for the switch.

[jfmherokiller]

What I have been attempting for the past few hours has been a kind of basic telnet client so users can watch "towel.blinkenlights.nl" on their switch.

In order to avoid reinventing the wheel I attempted to use the telnet source code found here https://l3net.wordpress.com/projects/simpletelnet-project/

My current version of the stelnet.c file can be found in this gist https://gist.github.com/jfmherokiller/53279e9251b5dd0c463ec8028df7192e

I believe I made some kind of progress by applying the nxlink example code. however I seem to have hit an issue im not sure how to go about fixing.

The issue seems to be "Select. Error: Socket operation on non-socket".

This error seems to crash the console as well which makes testing it tedious because i must reenter rcmmode on my console every time.

If anyone has any helpful input please respond because my googlefu isnt turning up any reliable results.

~~Update~~

I got it working and the latest version of the code is at the gist link.

~~update~~

included the cmake files i used to compile the code and attached the nro to this post.

I do not have a pretty icon or anything for it since this was meant to be a one off kind of thing to test switch homebrew and my coding skills.

~~update~~
feel free to use this code as a kind of example for working sockets on libnx

~~update~~

File loading portion completed.
now to make use of it put a telnet.conf file in the /switch folder

the format of the file is

<server hostname here>
<port here>

I succeeded in a kind of proof of concept

this is exactly that. I worked on this little telnet thing as a sockets test for libnx

rn im actually trying to also include hostname resolution via gethostbyname so that I only need to hardcode the hostname. Ill update the gist if i succeed.

Great work. I look forward to the outcome

I got gethostbyname working and moved it to a separate function.

I think its technically complete now.
Only remaining issue is that im unable to figure out how to handle the vt100 codes the server sends. so you see the escape codes on the screen.

I would kind of like to post the nro for people to play with but im not sure if i can post it here.

But I think ill update the gist to show what i used to compile it so others can possibly do it themeselves.

you should be able to post as it doesnt contain any copyrighted material. if you report you OP and ask to be a release the mods will fix. Great work btw
It would be cool if you include or link the star wars asci movie

linked in the original post and give me a short while to get the nro and ill also attach it to the main post

I'll now see if i can implement a simple file loader so that the telnet client can be told to connect to a specific server.

Completed the file loading part
